MEANS FOR OVERCOMING THE TRANSMISSION OF CONCUSSIONS T0 VEHICLE FRAMES0R BODIES.

SPECIFICATION forming part of Letters Patent No. 793,165, dated June 27,1905.

Application filed January 28, 1905. Serial No. 243,133.

Be it known that I, COLOMAX S'rnmx, a subject of the Emperor ofAustria-Hi1ngary, residing at Vienna, Empire of A ustria- Hungary,

5 have in vented certain new and useful Improvements in Means forOvercoming the Transmission of Concussions to Vehicle Frames or Bodies,of which the following is a specification.

This invention relates to an apparatus that can be applied to allvehicles running on wheels, by means of which the vertically upwarddirected concussive movements due to unevenness of the roadway arecompensated by means of a force originated simultaneously and acting ina vertical downward direction in such a manner that the said concussionscan have no effect on the framing or on the body of the vehicle.

In the accompanying drawings, Figure 1 shows a front view of thearrangement, the parts being shown at rest and the axle being shown insection. Fig. 2 shows a plan of the same.

As can be seen from the drawings, to the axle A is rigidly lixed asliding piece l3, which serves as guide for the axle in working in theslot S of the plate G. This sliding piece is provided with two bosses atand 7), in which are mounted the pivot-bolts p and c of the tension-rodsI) and F. These rods are connected by pivot-bolts and 1 with theelbowlevers O, that are pivotally mounted at u on the fixed plate G. Thelevers O act upon the volute springs E by means of guide-bolts fi',pivotally mounted at The levers O, rods 1) and F, and springs E arearranged symmetrically on each side of the axle A, and the springs areinclined downward toward 4 each other, preferably at an angle oftwentytive to thirty degrees to the horizontal plane.

When a concussive force acts upon the axle A, this moves up in thedirection of the arrow ,1 in the guide-slot S of the plate G andtransmits the force of the concussion, by means of the rods 1.) and F,directly to the bolts r and 1 of the ellmw-levers C, the motion beingtransmitted first through both rods L) and F simultaneously and in thefurther course of the movement, in consequence of the 5 difference inlength of the arms of the elbowlever, through the rods F only. Duringthis part of the movement the longitudinal slots (Z of the rods D areshifted with regard to the bolt 1). By this means the lovers O areturned and the volute springs E are compressed. 'hen the concussiveaction has terminated,

all the parts are brought back to their original position, andconsequently also the axle A, by the expansion of the springs E. Thisconstruction of the apparatus has the effect that on the one hand theconcussive force is compensated by means of a force which is originatedsimultaneously and which acts in a vertical downward direction, asindicated 5 by the arrow and on the other hand that the springs are onlystrained with a part of the force resulting from the axial pressure ofthe vehicle, so that they can be comparatively weak, and thereforesensitive.

As above stated, the two pairs of rods 1) and F act in the commencementsimultaneously, whereas during the latter part of theway which thelevers O make during their oscillation the latter is acted upon by thepair of rods F only. By this arrangement the effect is obtained that theconcussive force is at first transmitted to the springs E by means ofthe long arm of the lever O, and therefore with great sensitivity; butwhen the concussive 30 force increases beyond a certain limit it willact through the rods F upon a smaller leverarm, so that in this mannermostvigorous concussions can also be transferred to the said springswithout overstraining the latter.

I claim* 1. An apparatus for overcoming the transmission of concussionsto vehicle-bodies or the like comprising a plate, an axle support, meansfor vertically guiding theaxle-support 9 in said plate, a bell-cranklever on eachside of the axle-support and pivotally connected to theplate, one set of oppositely-disposed links connecting the bell-cranklevers with an upper point of the axle-support, another set ofoppositely-disposed links connecting the bellcrank levers with a lowerpoint of the axlesupport, and springs connected with the bellcranklevers which normally tend to react against the upward movement of theaxle-support. I

2. An apparatus for overcoming the transmission of concussions tovehicle-bodies or the like comprising a plate, an axle support, meansfor guiding the axle-support in said plate, a pivoted lever supported inthe plate on each side of the means for guiding the axlesupport, one setof links connecting one of the ends of each of the pivoted levers withthe axlesupporting means, a second set of links connecting the other endof each of the pivoted levers with the axle-supporting means, andresilient means cooperating with the pivoted levers which normally tendto react against the upward movement of the axle-support.

3. An apparatus for overcoming the transmission of concussions tovehicle-bodies or the like comprising a plate, amovablc axle, means forguiding the movable axle, a pivoted lever on each side of the means forguiding the movable axle, oppositely-disposed links connecting one armof the pivoted levers with the movable axle, another set of linksconnecting the other arm of the pivoted levers with the movable axle,and means cooperating with said pivoted levers for reacting against theupward movement of the axle.

4. An apparatus for overcoming the transmission of concussions tovehicle-bodies or the like comprising a plate, a movable axle, a slidingpiece for the axle, means for guiding the sliding piece, leverssupported in bearings, one of said levers being on each side of themeans for guiding the sliding piece, oppositely-disposed links having atone end a pinand-slot connection with the sliding piece and at the otherend a pivoted connection with one arm of the levers, a second set ofoppositelydisposed links having one of their ends pivotally connected tothe sliding piece below the pin-and-slot connection and their other endsto the other arm of the levers, and means cooperating with said leversfor reacting against the upward movement of the axle.

5. An apparatus for overcoming the transmission of concussions tovehicle-bodies or the like comprising a plate, a movable axle, a slidingpiece for the axle, means for guiding the sliding piece in said plate,levers supported in hearings in the plate, one of said levers being oneach side of the means for guiding the sliding piece,oppositely-disposed links connecting one arm of each of the levers withthe sliding piece, a second set of oppositely-disposed links having oneof their ends pivotally connected to the sliding piece below theconnection of the other links and their other ends connected to theother arms of the levers, and a spring reacting against the levers toretard the upward movement of the sliding piece in its guiding means.

6. An apparatus for overcoming the transmission of concussions tovehicle-bodies or the like comprising a plate, a movable axle, a slidingpiece fixed to the axle, means for guiding the sliding piece, leverssupported in bearings, one of said levers being on each side of themeans for guiding the sliding piece, oppositely-disposed links one oftheir ends having a pin-and-slot connection with the sliding piece andtheir other ends connected to oneof the arms of the levers, a second setof links having one of their ends connected to the sliding piece belowthe pin-and-slot connection of the other set of links and their otherends connected to the other arms of the levers, and springs reactingagainst the plate and levers.
